The Bathhouse building was built in 1939 as a joint project of the City of San Francisco and the New Deal Works Progress Administration (WPA), and is the focal point of the Aquatic Park Historic Landmark District. This unique structure was designed in the Streamline Moderne style, a late offshoot of the Art Deco period, and mimics the clean lines of an ocean liner.
